My Addon domain has ip. My node monitors HyperText Transport Protocol using ip. It can directly see the page without adding ports. I tried other ports myself. I bound 3000 ports as long as ip or domain name is followed by: 3000. If I monitor 80, how can I access the domain name directly?
Configure a reverse proxy server for distribution, which can use nginx, apache. Even write directly with nodejs, the recommended npm module is http-proxy, you can try it.
